Empty Town

These photos were taken by the Pentax 110 Auto 24mm lens mounted on the Sony A7R-4 camera, while I took a shopping tour to the centre of London through rock downed empty street. (When I need to get a soy source, I have to go Japanese food shop in the centre.)

As you might have guessed, the advantage of this lens is its small size = almost like a body cap. Together with small mirrorless camera, they easily slip into my pocket. Why do I need to use heavy big lens instead ?

Sony Extension Ring

To prevent the close contact, the postman left a percel from China outside of my door while shouting Your Post = I got an Extension Ring delivered today.

To have an even closer shot, the Extension Ring is a pretty handy device. You may find such ring for Sony (10 mm and 16 mm set) as cheap as £15 on eBay. And depend on the lens used, you may get quite a close-up photo (the shorter the focal length the closer you get —– though, depend on the lens, the closed image might be pretty bad unless you stopped down the F-aperture a lot.

With such a cheap price, I bought 3 or 4 set of Sony Extension Ring. Since, I discovered, not all of them are good. Some loose bayonet make the joint wobbly (only 0.1 mm wider gap of bayonet makes it loose) —– even worse, some of them stack solid (only 0.1 mm longer bayonet claw can block them disengage) = To separate the camera body — Ring — Lens, I needed to hack-saw the ring and with sheer force, I ripped off the Lens ! (Photo above right two = used be the DG-NEX Extension 16 mm ring = the left over after a hack-saw job.) The trouble is, you discover the trouble only when you HAVE engaged the Lens – Ring – Body. = Then you realised that you got the trouble of stacked bayonet. —– Because of the internal mechanism of the bayonet, we can’t see which part was blocking the ring to rotate back.

This IS what made in China meant. On the eBay, you may see many “Sony Extension Ring” with different prices —– Give close looks = The ring came from only few original manufacturer, then, different vender selling it in a different price. = Expensive doesn’t mean good quality. Manufacturer seemed to sold off bad lot for give-away price then, corrupt vender sold them in the net, expecting most of the customer never bothered to complain for £15. —– So, on the end I bought plastic one = Easier to hack-saw and when I needed, easy to brake-off before the lens or the camera body brake. (Sound dreadful isn’t it)

Those potos were taken by the Sony E 3.5 / 30 mm Macro lens with Extension Ring on A7R-4 body (see a photo above, before) Right hand side image was a cloped enlarged part of the original photo left.

So, when you are lucky to have good working Ring you may get quite nice close-up photo —– especially with such A7R-4 / 62MP image sensor, we can clop the image for even higher magnification scale. (Otherwise, such as x5 ~ x10 magnification needs to have quite a hard work — and a specialised expencive Macro Lens.)

How to deal with Cold,Flu,C-19 Granny’s way

They are the advises made by Dr.Med Seiji Ishigro (by a Ytube Viz) which was told by granny.

• When you caught cold (or Flu, C-19) stay in a bed and keep you warm. (= Body’s immune system needs higher body temperature to work. = When you were cold You get Cold)
• Stay in a bed mean, you have to be laying down to have better condition of blood circulation and the ease of your guts. Because of the body’s immune system / antibody was produced in the intestine.
• Body temperature was rose by the body, not a toxin of the virus = because it needs higher temperature for the antibody to work. Body themselves knows this, hence rose their own temperature. = It’s mean don’t use the medicine to lower the temperature.
• Eat well such as Kiwi, Lemon for the vitamin C. Good Cholesterol (meat, egg, cheese etc) and the mushroom for the vitamin D.
• Don’t panic = You may get well soon when you stay in a bed for few days and get sweat for one night = It’s a cold. Million of years we’ve been with them, still we are here surviving.
• (Though, if it didn’t work, don’t come back here to brame Dr Ishigro, he was told by the local granny, it’s a cetury old granny’s way)

Macro shots (2)

On this post, all the shots were made by Pentax 110 Auto 24 mm lens on Sony A7R4. And looks like macro shots were the heavily cloped small part of the original photo’s part enlargement —– can you find where it’s came from ?

So, it is clear, a lens I bought for £5 from a junk box, Pentax 110 Auto 24 mm lens has the quality of the (almost) top lens, and the 60MP image sensor of Sony A7R4 can capture (almost) whole amount of those visual information there. Therefore, a wide angle casual shot of a 24 mm lens was in fact, holding the details of the macro level too.

Pretty Good isn’t it ! So, I like this Pentax 110 Auto lens on the Sony A7R4 camera always in my pocket. 😀

Macro shot ?

Z55 – A7R4

Once before I found a trouble of manual focusing in the Sony camera. So, I was testing Zeiss 55mm lens on A7R4 body with Focus peaking and the Focus magnifire. —— This time both function worked well = AND I amazed by its fine details of the captured image. = The silk flower was 100 cm away yet the enlarged image showed a real close-up = macro quality.

Z55 – A7R4

I wonder IF this fine quality came from the quality of the Zeiss Sonner FE 1.8/55 ZA lens or the camera’s 60MP image sensor ?

AI Nikkor 50 – A7R4

For comparison, this one was AI Nikkor 50 mm F1.2 (at F1.2 / 100 cm) on A7R4 (this 50 years old 50 mm lens seems to be a bit softer than Zeiss 55 mm —– But, F1.8 lens got to be sharper than F1.2 !)

AI N 50 – N Z7

Then, how about the AI Nikkor 50 mm F1.2 lens on Nikon Z7 ? It’s haed to tell if a bit softer image was caused by a larger F aperture (F1.2 instead of F1.8) or a bit fewer pixel number (46MP instead of 62MP).

P110-24 – A7R4

On the same setting, I tested it with the remotest possible lens = Pentax 110 Auto 24mm F2.8 lens === 24 mm lens image was far smaller than the 55 mm lens. Still, the enlarged image showed quite a fine detail !

It’s suggests that as long as the lens was seriously designed good lens, its can produces very fine details = IF the resulting image was not very fine, it was because, the camera / image sensor / image processer was not good enough.

P110 – NZ7

This is the comparison = The same Pentax 110 lens was mounted on the Nikon Z7 body through a homemade NEX – NZ adapter. —– Even though the same optical image was projected, the smaller sensor seemed to produces a bit rougher image.

Godo – A7R4

So, see the image of the lens which was not seriousely designed or made = homemade Godo-lens.

NZ-B – N-Z7

Then, how about the image made by yet another fine camera Nikon Z7. —– But (you believe it or not) I don’t have an authentic lens for this Z7. (I’ve been empoverished by its XQD memory (made by Sony), expensive spare battery etc —– I can not afford to buy their lens.)

So, the Z7 camera was tested with another homemade lens, NZ-B lens which showed very fine undefined image !

Daikon 2020

So, I’m watching the same windowscape of my kitchen window.

Only a difference in these days was, the leaves of the Daikon head. Which was growing well. Some of you might say that I can cut them small and eat or put in a Miso soup —– I know. But I want them to live free and grow. (I’ve tormented the Daikon root badly enough, boil her alive and eat = I need to make a hypocritical excuse by humainly saving the leaves)

It’s a spring. (Forget the hell outside or the world beyond)

So, the Daikon is having her flower bud —– though, would the flower open or not is the different story.

https://yoshizen.wordpress.com/2017/05/17/daikon-flowers/

When she got 30cm tall, before opening the flowers, she lost a vigor of the life. I couldn’t see any reason why, —– it was same as last time. How shame. (May be I need to learn about the Daikon plant start from its seed, not the left over top of a Daikon food.)

MP Cherry 2020

Those photos of the Multi-petal Cherry was taken by a homemade lens, NZ-B lens on Nikon Z7

May be in a normal sense, such lens may not serve for a photographical use. Yet still, any image could be an image as long as the author = I wanted. Why not ?

Under the COVID-19 pandemic, our activities and the movement has been restricted, so the picture I am producing may looks one pattern too. (Sorry)

The lens NZ-B seemed to have two glasses of which I re-mounted into a zooming barrel and able to focus from infinity to 1/3 close-up. Still, born to be a simple junk lens the image never be sharp. —— But that was what I wanted. 😀

Requiem

Those screen shots of the Youtube viz was made with Canon 5D-MkIII, EF 40mm F 2.8 set manually to F5.6, 1/8 ~ 1/30 Sec’ = ISO was selected to enable this exposure.

Under the restriction we stay at home —– to spend more time with internet. = So, I encountered one of the most distinguishable, Morzart’s Requiem which was packed with the strongest anger ( = no sobbing, or asking mercy but an explosion of the anger — may be toward the God) But, mind you this recording was made 2014 —– I think the Venezuela was not in the hell (yet). And this is not my sarcasm toward the COVID-19 trouble we are having. (Timing was purely the coincidence) — but, my coincidence was always having had the message = the God may be angry.)

The musisians of this orchestra and the choir must be the ethnically the most diversified members — that’s what I noticed.

In my view, the Requiem is only a music Mozart created for himself with his true sentiment. (Others were just a commercial products to buy a favour of the society)

(Morzart said to be a member of the Free Masons though, when he died even before completion of this Requiem, nobody helped his funeral and he was buried to a common grave. — was this what he deserve ?)

—– yet still, there seems to be the reason why. Unlike what you believe, the real life of Mozart was nothing like a decent kind, but a hopelessly disorderly man = loose on the money and drunk which pushed all of his friend to forsake him = so, when he faced the death, he must be aware what to expect = the reality of the own fate = the reflection of own making. He must have had enough anger toward himself, much much more than toward the God who he never seen.

How NOT to get COVID-19

This was a tweet which has been Re-tweeted 100.000 times in two days,

[the advise, how NOT to get COVID-19 infected] made by a (Prof) Takayuki Miyazawa（宮沢孝幸准教授） of the Virus study, Kyoto Uni’, Japan

(1) Think, you were a person already infected by the COVID-19.

(2) And Think, try NOT to infect others.

(3) Breath through the Nose. (not by the mouth)

(4) Don’t touch your Nose, Eyes, Mouth while you are out.

(5) While you are eating, just eat, NOT to SPEAK (or Talk)

(of course, those MIND-SET were on top of the ordinary precaution = What to DO, such as [Wash your hand] [Keep a distance to each other] etc ——- may be because of those mind set and the attitude, the number of the infected in Japan is (on 30-03-2020) only 2.700 cases so far.

Stay safe and keep you well.

A kind of Tree

It seems most of those trees are Oregon Maple in their winter guise.

The lens used was homemade NZ-B lens on the Nikon Z7

Now the street was deserted —– may be because of the spread of the COVID-19, which was said to be 8.000 cases, 400 death in this country, — what can I say.
